Question 13 of 28

13. Question

13 A network engineer has configured a router with the command ip nat inside source list 4 pool corp overload. Why did the engineer use the overload option?

The company needs to have more public IP addresses available to be used on the Internet.

The company has a small number of servers that should be accessible by clients from the Internet.

The company has more private IP addresses than available public IP addresses.

The company router must throttle or buffer traffic because the processing power of the router is not enough to handle the normal load of external-bound Internet traffic.

Correct

Incorrect

Question 18 of 28

18. Question

18 Several key servers in an organization must be directly accessible from the Internet. What addressing policy should be implemented for these servers?

Use dynamic NAT to provide addresses for the servers.

Place all of the servers in their own Class C private subnet.

Use DHCP to assign addresses from the pool of Class B addresses.

Assign static internal addresses and public external addresses to each of the servers.

Correct

Incorrect

Question 19 of 28

19. Question

19 What is a characteristic of unique local addresses?

They are designed to improve the security of IPv6 networks.

Their implementation depends on ISPs providing the service.

They allow sites to be combined without creating any address conflicts.

They are defined in RFC 3927.

Question 22 of 28

22. Question

22. Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254 across a router R1 that is running dynamic NAT. (Not all options are used.)

Sort elements

R1 checks the NAT configuration to determine if this packet should be translated.

R1 selects an available global address from the dynamic address pool.

The cost sends packets that request a connection to the server at the address 209.165.200.254

If there is no translation entry for this IP address, R1 determines that the source address 192.168.10.10 must be translated.

Question 26 of 28

26. Question

26. A network administrator is configuring a static NAT on the border router for a web server located in the DMZ network. The web server is configured to listen on TCP port 8080. The web server is paired with the internal IP address of 192.168.5.25 and the external IP address of 209.165.200.230. For easy access by hosts on the internet, external users do not need to specify the port when visiting the web server. Which command will configure the static NAT?
